Re: Garrett Turbo on Evo

The turbo on the multiair is the same as the essesse grande abarth but is the manifold the same as the t-jet essesse manifold?

Re: Garrett Turbo on Evo

I wouldn't of thought so, they're different cylinder heads.

The standard Evo Multiair turbo has smaller turbo as used on non-Evo Abarth GPs.

Abarth Evo has the bigger Garratt turbo. The Abarth Evo EsseEsse therefore does too. Of the non-Evo GP's, only the Abarth EsseEsse has this turbo.

What manifold you have is only determined by which of the two turbo designs you have, not which car or engine spec otherwise. The Multiair head is a modification of the conventional head and retains most of it's external dimensions, including stud patterns. All heads/manifolds are interchangeable with each other with supporting mods.

Re: Garrett Turbo on Evo

Ah, so the sporting has a smaller turbo to the Abarth. I'm guessing then in order to get comparable power (as the TMC box does) the smaller turbo is going to be pretty much maxed out.

Re: Garrett Turbo on Evo

I believe its only a smaller turbo in comparison to the Evo Abarth, and is of a similar size to the standard Grande Abarth.
Best point to note is that its a Garrett on the Evo Sporting (and Evo Abarth) which is a top class turbo.

Re: Garrett Turbo on Evo

I'm thinking how hard it has to work (and reduced life) if I decide on a TMC box. Garretts have always been good, my previous car (Nissan 200sx) was producing 296bhp with a Garrett T28 and had done a very reliable 115k miles when I sold it and it still hasn't missed a beat. That was pretty much the limit for a stock T28 though.

I have my box set on a slightly lower power setting than the factory level which now in theory has the car producing a similar power output as the Grande Abarth. I donít by any means work my car hard or do a high mileage so for me itís safe and I havenít had any issues relating to the box or turbo. Something to remember though if you are considering the TMC box is you are advised to use the higher octane petrols to help protect the engine (Tescoís version is the best value).

I am afraid that I have pedalled an untruth a bit here.

The smaller turbo on MultiAirs is a small turbine Garratt as TJ07 mentioned, not the same IHI as used on earlier non-MultiAir engines. So substitute that into the first sentence of the original quote. The rest holds fast. The two basic manifold designs are Garratt or IHI and are interchangeable between spec levels of turbo.

Re: Garrett Turbo on Evo

I know I'm asking a lot, are the injectors and fuel pump the same between the sporting and Abarth?

Not entirely sure but if I recall correctly the injectors are slightly different between the twoÖ donít know about the fuel pump though.

Re: Garrett Turbo on Evo

Fuel pump is same for all FIAT and Abarth Grande Punto 1.4 Turbos (2007 until now). Injectors are same for all FIAT and Abarth Evos.

Re: Garrett Turbo on Evo

So the differences in power is purely boost. If I keep the car beyond its warranty and pcp agreement I'll be unleashing the extra horses!

If you mean the difference between the Evo Abarth and other Evos, then it is the turbos that have a different turbine (internal) design. This gives the Abarth a significant increase in boost at a higher RPM. This makes it less suitable for pottering about, but deliver more power at sustained full throttle. The programming of the valve timings will be significantly different with a bias to power also. I don't have any Evo engines, so I haven't researched the fine detail of the parts, but a quick look suggests that apart from turbos, there are few or no significant differences between Evo FIRE turbo engine internals apart from turbos as valve timing can simply be adjusted in the ECU for different specs.

Without the benefit of MultiAir, previous Abarth T-Jets, Bravo 150 and high spec Alfas had higher lift (I call them Abarth) cams as well as the larger turbos to give them an extra edge. Again, this had the effect of raising the power band up the rev range. Good power can be had from 1500RPM in a 120 T-Jet, but subjectively, I would say it is 3000RPM in a 150 or Abarth T-Jet. It's something to think about if you only very rarely want to cane it.
